LANTERN-DOME.

Application filed. August 29, 1928. Serial 1T0. 302,872.

This invention relates to lanterns, embodying among other characteristics, a ventilator adapted to discharge smoke and heat emltted therefrom.

5 Another object of the invention contem plates locking means connecting a globe retainer which may be readily disassembled from the ventilator when partially rotated.

With the above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing, and pointed out in the appended claim.

In the drawing:

Figure 1 is a vertical section taken through the ventilator and retaining means. I

Figures 2 and 8 are sectional views taken on lines 22 and 8-3, respectively, of Figure 1.

A dome-shaped cover or lid 14 is provided with a combined ventilator and globe retainer. An inner dome 15 is positioned within the dome-shaped member 14 and insulated therefrom by a packing 16, such as asbestos. Both of the dome-shaped members are foraminated.

The globe retaining plate 17, provides an annular seat 18 upon its under side and is positioned within the inner dome-shaped member 15. intersecting cross bars 19 pass throughan eye 20 provided in the lower end of a rod 21 which in addition supports a frustoconical shaped smoke deflector 22. The upper end of the rod 21 also provides a looped end 23 adapted for selective engagement with an offset pin 24 suspended and depending within the dome-shaped member 14. Said end is passed through a slotted portion in the upper portion of the inner dome-shaped member 15. A coil spring 25 encircles the rod 21 and has its opposite end convolutions engaging the inner dome-shaped member 15 and periphery of the globe retaining plate 17.

A slight twist of the dome-shaped member 14 and globe retaining plate 17 in opposite directlons, when the latter compresses thespring 25, will release the upper loopedend 23 of the rod 21 from the offset finger 24 suspended and depending from the dome-shaped member 14.

Manifest-1y, the height of the lamp or lantern, would naturally tend to overheat the dome-shaped member14, which oftentimes burns the hands when a swinging handle. is employed. The inner dome-shaped member 15 is insulated from the outer dome-shaped member and each of which provides foraminated side walls through which smoke and heat may pass, will overcome this difficulty slot within the upper end thereof, said members being telescopically associated and foraminated, a globe retalnlng plate carried within the inner member, a compression spring interposed between the inner domeshaped member and retaining plate, cross bars carried by the retaining plate, a rod engaging the intersecting portion of the cross bars for supporting the retaining plate against the tension of the spring, and said rod having an enlarged portion passing through the slot in the inner dome.

n In testimony whereof I aflix my signature.
